Abstract

The application discloses a method, device and system for eliminating background audio data, belonging to the technical field of computers. The method includes: obtaining audio feature information of current background audio data; sending the audio feature information of background audio data to a server; synthesizing current background audio data and collected audio data to obtain synthesized audio data, and synthesizing audio data and The current collected image data is synthesized to obtain synthesized video data; the synthesized video data is sent to the server; the synthesized audio data in the synthesized video data is extracted; in the audio library, the corresponding audio characteristic information is found to be related to the audio characteristic information of the background audio data Matching target audio data; based on the target audio data, performing background audio data elimination on the synthesized audio data to obtain audio data after elimination processing. With this application, background audio data can be eliminated.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device and system for eliminating background audio data. Background technique [0002] In recent years, the live broadcast industry has developed rapidly. Watching live broadcasts has become a very common form of entertainment for people, but there may be some illegal content in the live broadcast. [0003] The current technology for monitoring whether the live broadcast content of the anchor is illegal is to separate the audio in the live video for text recognition, and then determine whether the live content is illegal by detecting the recognized text. [0004] In the process of implementing this application, the inventor found the following problems in related technologies: Whether the live broadcast monitoring technology is effective mainly depends on whether the audio is converted into text accurately, and the background music used by the host during li...
